To all 107mm e't may Concern Be it known that we, ROBERT Asrmrnnn and Josnicrr Comms, citizens of the United States, residing Indian Orcharchin the county ot l-lan'ipden and State of Massachu sette, have i vented new and useful lmprovements in Yarn-finding Spools, ot which the following is a specification.

rIhis invention relates to improvements in spools onwhich strands of yarn that are to be used in weaving rugs. More particularly the invention has for an object reliable means Jfor temporarily clamping or securing the inner ends of these strands while they are being wound onto the spool. rlhe securing means is so constructed and arrangedthat it may readily be removed after' the spool has been lilled `with the strands ot yarn which are wound thereon in the usual manner.

A further object is to provide means which cooperate with the yarn holding means for driving the spool by applying rotative movement directly to the two ends of the yarn r holding means.

l-leretofore, it has been a common practice to directly apply the driving power only to the ends of the yarn winding spool with the result that these spools are often broken due to the twisting or torque stresses which are imparted to the spool when only the ends are utilized for driving the spool. On account of the excessive breakage of the spools and the cost of replacing them the present improvement has been developed. lt has also been a common practice to apply the driving only to end ot the spool.

The invention, broadly considered, com prises a cylindrical member, preferably ol. wood, which is formed with a longitudinal groove throughout its length. In this groove is placed a. rod for the purpose of clamping the inner ends of the strands of yarn to the cylindrical member. Secured to the ends of this member are disc-shaped pieces, which pieces are formed with transversely located openings that are located in alignment with the opposite ends of the groove in the cylin drical member, whereby the yarn clamping rod may be inserted in and removed from the groove. The ends of the rod are formed with cutaway or reduced portions for the purpose of forming shoulders which will engage a suitable tool orlirmly retaining are wound` the rod in a fixed position when therod is to be removed. The removal operation consists in imparting a lengthwise pull on the spool will be described.`

Referring to the drawings:

Fig. l is a partial sectional plan view showing the clamping rod in place in the groove to retain the ends of the strands orl yarn in place. vAlso, the reduced end por-` tions of the rod and the driving means forl the spool.

Fig. 2 is a transversesectional `view on the line 2 2 of Fig. l, showing the rod in the groove and the strands of yarn under the rod and in the groove, and

Fig. 3 is a detail perspective view of one end of the discshaped member, also showing a portion ol' the'cylindrical shaped member and groove therein.

Reterringto the drawings in detail:

l designates the cylindrical or barrel part of the spool which is formed with the longiV tudinally Var 1anged groove 2 through its length. It is preferably rectangular in cross section, as shown in Fig.A 2. 3 and 4 are disks which are secured to theends of the barrel part. These disks are each formed with a part 5 which enters a recess inveach of the ends oft the barrel part. Pins 6 are provided for securing the disks 3 and 4l to the ends of the barrel. Each `disk is also providedwith an outwardly extending projection 7 having the oppositely located flat Yfaces or surtaces, as shown. These projections are designed to enter openings 8 in the spool driving members 9. l0 designates a rod which is circular in cross section which is designed to be placed in the groove 2. fhis rod is formed at each ol its ends with the reduced or eutaway portions l1 and 12 which produces the head pieces 18 and shoulders lll. vThese reduced portions and shoulders are 'tor the purpose of providing' retaining means ior holding the rod in a lined position when the rod is to be removed by inserting it in a suitable clamping or gripping device as a special shaped slot in a fixed plate whereby when the operator grasps the barrel l and pulls longitudinally of the same, the rod may be removed from the groove 2.

Each disk is formed with an opening 15 through which the ends of the rod normally extend as shown.

The ends of the strands 1l of the woolen yarn which are tobe temporarilyelamped are first laid across the groove 2. The rod 1G is then placed over or on these ends and forced down into the groove Qearrying the strands With it. The spool vlis then ready to be rotated for Winding the yarn onto the same until it is completely filled.y The rod l0 is then removed in the manneras already described thus leaving the inner ends free to unwind when the spool is placed vin a rug weaving machine.

Thebarrel part-1 is understood to be of considerable length and heretofore often breaks due to torsional stresscs,but b y emf ploying the rod l0, which is placed in the .the longitudinally extending rod `l0. The

torsional str sses are therefore equally distributed throughout thelength of the barrel member l.

After the spool .is filled the rod is removed, thus leaving the inner ends of the yarn free to unwind Without any loss due to breakage.

3i/'hat We' claim is:

l. A yarn winding device Comprising in combination, Va grooved barrel member, drivingmeans secured to the ends of the member, andformed with openings which extend through the driving means, a yarn strand clamping rod'located in the groove land having its ends extending through the openings in the/driving means; said extending ends .means `to drive thelspool for exerting a uniform driving effort throughout the length of the spool, whereby torsional stresses are eliminated.

A Winding spool comprising a barrel member `vvhioh is formed vrith a groove throughout its length, a yarn clamping memberinrthe groove, the clamping member having shoulder portions near its ends for removing the same, means for imparting rotative movementto the spool,` and Cooperating means between the rotative means and the yarn clampingmember.

4L. A Winding' spool for the purpose described, having` in combination, a grooved barrel member, discs seouredto the ends of the member and formed Withopenings in alignment with the groove in the barrel member, a clamping ro'din the groove with
